The values specified for the above servo motors in the selection tables of the servo motor catalogue are based on operation at a chopper frequency of 8 kHz. Operating these servo motors on the 9400 at chopper frequencies with fch = 4 kHz is possible with the following restrictions and effects:
Motor typ Operation on inverters at chopper frequencies fch = 4 kHz
MDFQA 160 Effects
▪ With fch = 4 kHz, the motor will permanently only provide approx. 95 % of its rated torque.
▪ Intense increased noise emission.
MQA 20, 22, 26 Effects
MCA 20, 22, 26 ▪ With fch = 4 kHz, the motor will permanently only provide approx. 95 % of its rated torque.
▪ Increased noise emission.
MCA 10, 13, 14, 17, 19, 21 Effects
MCS ▪ none
